Huldra Arms is Adams Arms brand using their proprietary piston system. Every review on Adams Arms drop in piston systems I have seen has been positive for the most part, so the upper should be ok. Just a reminder, do your own research. With all the hoopla about piston AR's, like anything else, there are some companies making good products, and some make crap. There are companies out there making DI system guns that are just as reliable because the QC is better than other companies. Personnaly, if I were to buy a complete piston upper now, I would probably go with LWRC. They got a longer track record on the piston AR's, and POF is way too expensive.
